Punit lives on the floor numbered five. Only two people live between Punit and Kunal. Kunal lives above Punit. Tanu lives immediately above Reenu. Only one person lives between Tanu and Ajay. Tanu lives above Ajay. Clearly, we can’t place Tanu immediately below Kunal. So, two cases are possible. Vicky lives immediately above Sahil.
Usha lives on an odd-numbered floor. As in Case II only even numbered floor is left to be filled, hence, Case II becomes invalid. So, Usha must be living on 1 st floor.
B is 5 years older than A and A is 7 years older than C. If the sum of the age of A and C is 21 years, then find the sum of the ages of all three.
The ratio of A and B present age is 9:4. The product of their ages is 3600. What will be the ratio of their ages after 5 years?
Sum of the present ages of A, B, C and D is 60 years. After 6 years ratio of their ages is 6:5:5:4. What is C’s present age?
